Schema Checking

Generally,
schema checking is performed by the server that exposes the schema. In a scenario
where Directory Proxy Server acts as a proxy to one or more Directory Servers,
the Directory Servers check that add and modify requests adhere to their
LDAP schema. When Directory Proxy Server exposes its own schema. Directory Proxy Server must
check that add and modify requests adhere to these schema.

Because a schema is defined for a specific connection handler, schema
checking is enabled per connection handler. Schema checking is enabled by
setting the schemaCheck attribute of a connection handler
to true.
